compile error about destructor |
Hello everyone,
When change from __try to try, and __except(GetExceptionCode()) to
catch(...), compile can pass.
Compile error and code are,
1>Compiling...
1>main.cpp
1>d:\visual studio 2008\projects
\test_exception1\test_exception1\main.cpp(30) : warning C4509:
nonstandard extension used: 'main' uses SEH and 'foo1' has destructor
1> d:\visual studio 2008\projects
\test_exception1\test_exception1\main.cpp(28) : see declaration of
'foo1'
1>d:\visual studio 2008\projects
\test_exception1\test_exception1\main.cpp(35) : error C2712: Cannot
use __try in functions that require object unwinding
[Code]
#include <iostream>
#include <excpt.h>
#include <windows.h>
using namespace std;
class Foo
{
public:
Foo()
{
cout << "constructing Foo" << endl;
}
virtual ~Foo()
{
cout << "destrucing Foo" << endl;
}
};
int main()
{
int* address = NULL;
__try{
Foo foo1;
(*address) = 1024;
} __except (GetExceptionCode())
{
cout << "access violation caught" << endl;
}
return 0;
}
[/Code]
regards,
George

This has nothing to do with C++ as discussed in this group.
Try a group with MICROSOFT in it's name.
However, that being said, it looks quite obvious from the error that
__try can't handle having any variables that need C++ destruction
semantics to be invoked.
You can map structured exceptions to normal C++ extensions (it takes
a few steps). Again either read the farking manual or go to the
appropraite group.
